摘要：

We present results suggesting that magnetic monopoles can account for chiral symmetry breaking in abelian gauge theory. Full U(1) configurations from a lattice simulation are factorized into magnetic monopole and photon contributions. The expectation [<(psi)over bar>psi] is computed using the monopole configurations and compared to results for the full U(1) configurations. It is shown that excellent agreement between the two values of [<(psi)over bar>psi] is obtained if the effect of photons, which "dress" the composite operator <(psi)over bar>psi, is included. This can be estimated independently by measurements of the physical fermion mass in the photon background. (C) 1998 Elsevier Science B.V.
